GENERAL CATALOG
The CNF41 . CNH41 series is a 3-terminal EMI filter for SMT based on multilayer chip capacitor technology. This CNH series is
for reducing EMI noise on DC power lines.
• Due to its small size and low residual inductance, it performs noise reduction at higher frequencies than conventional capacitors.
• High current rating (~2A) makes it well suited for reducing EMI noise on DC power lines.
• High capacitance (~0.22 F) enables reduction of noise over a wide frequency range.
• Nickel and tin plated barrier terminations offer good solderability and resistance to soldering heat.
• RoHS Compliant.
a
Applications
Noise reduction for signal lines and DC lines in computers, computer peripheral equipment, digital TV, DVD recorder, cellular tel-
ephone, automotive electronics, printer, FAX, etc.
